MPN #: P58358-H21-OS
When your server keeps crashing under heavy workloads, the missing piece is often reliable memory that can catch errors before they cause downtime. Origin (P58358-H21-OS) 64GB DDR5 4800MHz RDIMM 2Rx4 ECC RAM for PC/Server is a registered DIMM module that delivers error-correcting capacity and high-speed DDR5 performance, keeping your NAS or storage server stable and fast.
This module is ideal for data-intensive environments such as file servers, virtualisation hosts and high-availability storage arrays, where large memory pools and error correction are essential for continuous operation.
Choosing this Origin RDIMM means you get a memory solution that matches your server’s specifications without the premium price of OEM parts. The 64 GB capacity gives you ample headroom for virtual machines, databases and large file caches, while the registered design improves signal integrity on high-density boards. With a slim 3.8 mm depth and a light 100 g weight, installation is straightforward and does not add bulk to your system.
The module also meets RoHS compliance, ensuring it is environmentally responsible. Its operating temperature range of 0 °C to 85 °C and storage tolerance from -25 °C to 95 °C mean it can handle the demanding conditions of data centres and edge deployments alike. By opting for this matched memory, you avoid compatibility headaches and benefit from a product that is guaranteed to work with your target hardware.
